True Circuits' Phase-Locked Loops Used by ARM in Verification of
Microprocessor Cores

LOS ALTOS, California - October 8, 2001- True Circuits, Inc. (TCI), a
developer and marketer of innovative high-speed analog and digital
integrated circuits (ICs), announced today that it has signed an agreement
with ARM [(LSE: ARM); (NASDAQ: ARMHY)], the industry's leading provider of
16/32-bit embedded RISC processor technology, to supply PLLs for use in the
verification of ARM® microprocessor cores. ARM will use the latest
generation PLL designs from True Circuits to provide the reliable and
low-jitter clock functionality they require on their test chips for
leading-edge processes.

"ARM chose TCI because of their expertise in PLLs and the proven nature of
their PLL designs," said Ken Reimer, Porting and Foundry manager at ARM. "By
going with TCI in the future, we feel we can spend more time designing our
embedded cores and less time doing test chip integration work."

"We are pleased that ARM has decided to join the base of customers and
partners that will be using our latest generation PLL designs," said John
Maneatis, president of True Circuits. "ARM's industry-leading,
high-performance and power-efficient RISC processor cores and SoC designs
are a perfect match for our low-jitter PLLs. The use of our PLLs in ARM test
chips will facilitate the verification of their products and give us another
strong partner to demonstrate the robust and versatile nature of our PLL
designs."
